Systems and methods are disclosed that relate to network security within a virtual network, and how to add microservices in a scalable virtual network. For example, one embodiment discloses a method of receiving a deployment request to deploy a security microservice in a security service, the deployment request including a deployment specification. The method further includes determining whether an interface microservice is available on one or more hosts by accessing one or more host records for the one or more hosts, and selecting a host on which to deploy the security microservice utilizing the deployment specification. When the interface microservice does not exist on the selected host, the method further includes initializing the interface microservice on the selected host, attaching the interface microservice to a hypervisor of the selected host, connecting the security microservice to the interface microservice of the selected host, and deploying the security microservice on the selected host.
